As soon as you start the game you will be trained by Gaz, who will introduce you to basic controls and fundamentals. He will point you to a warehouse, follow the onscreen HUD to the location. You'll meet Cpt. Price and the rest of the team, he'll instruct you to complete the assault course. Simply complete it (it's not all too challenging) and you'll be prompted to select a difficulty. Choose which ever one based on which playthrough you're doing. After another small talk by Cpt. Price your screen with fade out, this is when it should unlock.

The first mission after the initial training. You will have to make your way through the cargo ship, dealing with anyone inbetween. After you've reached the end of the ship, you'll open a large cargo holder. Inside will be the objective. Collect the data and ship will begin to sink. Don't panic! Simply follow Cpt. Price and the others to the surface. I would reccommend you stay close because it is easy to get confused and lose direction. Once your on the bay, head for the chopper awaiting you for collection and jump! Don't just run at it. Hey presto, the achievement is yours.

You'll be sent to retrieve Nikolai and escort him to safety. Make your way through the level until Cpt. Price orders Gaz to 'Kill the Power'. This is where you'll locate Nikolai. Enable your Night Vision, make your way inside whilst taking out any enemies on your way. Nikolai is on the second floor, in a room bruised on the floor. Help him up and escort him to the Helicopter outside. There is no resistence outside or towards the pickup. Simply get and there you have it.

During the 'Bog' mission, after you were ordered to destroy the tanks patrolling on the highway bridge with the Javelin, you'll make your way towards an area, through a series of allies, where a tank - codenamed "War Pig", is under heavy fire. There will be alot of resistence. Try and relieve the pressure from the tank and take out the enemy. You'll be told to go towards an Anti Aircraft gunner, dispose of it and call in a friendly chopper. Follow the onscreen HUD towards the objective, it won't be too hard, use the route through the shops towards the side of the level. Approach the gunner, kill the few soldiers that will be around it, plant the C4 and get a safe distance away because the explosion will kill you.

After this, your HUD will update with a new objective. This is the easy bit. Make your way there, call in the friendly chopper on the building which is heavily dense with enemy resistance and watch the fireworks.

Easy mission. You'll take control of an AC-130 Gunship. Simple follow the instruction that you will be told. The only tip I can give for this is; watch your team. Do not confuse them with the enemy. Friendlies will show up as flashing strobes on the ground floor and appear to 'blink'. After the ground forces are flown to safety, the achievement should pop.

You will start at the bottom of a large village. Make your way to each different building in a counter clockwise motion. Your team will shout "Floor Clear" and "Building Clear" as an indication of wether they have found Al-Asad or not and how many enemies (if any) remain to be delt with. You will have too clear each building, no matter what, so you can't just skip to the 'correct' one.

You'll have the aid of Makarov's Pavelow at your disposal. It is on a 2 minute cooldown. Use it on a building before you enter it or the tanks which will be patrolling. Just to make your life easier. After you've cleared every building, you'll find Al-Asad and an ingame cutscene will commence. You'll get the achievement shortly after.

Probably one of the most challenging levels in the game. You will be on top of a block of flats. You'll need to snipe Zakhaev. When trying to snipe, watch the direction of wind. Wait for a stable wind current and take the shot. You will always hit his arm, no matter where the bullet lands, it's story related and inevitable. After you've shot him. A chopper will block your view - dispose of the pilot by shooting him down. When the chooper whirs out of control, get up and make your way to the back right corner of the building and rappel down by holding

From now on, you can run through. MacMillian is invincible and will catch up. Kill enemies on the way to relieve some pressure from you and get to safety. You'll enter some flats. Flashbang before you go in to be sure. After you exit the flat, you'll have to eliminate a small wave of enemies. Do so and prepare to take out a chopper. Almost the exact one you took down earlier. Shoot it down, just like before. It will whir out of control towards MacMillian and cripple him. From now on, you will have to pick up and put down MacMillian by holding

Don't steer to far otherwise you will fail. He can offer cover fire and is invincible. Make your way to the carnival, put MacMillian and prepare for a very long fight. When the carrier has arrived, grab MacMillian and head into it. Mission Complete.

Straight forward. Do as Cpt Price says, follow your HUD and keep your eye on the prize - Zakhaevs son. Don't lose him! Keep close but do not kill/shoot him. You'll chase him into some flats whilst taking out resistence on your way there. Just keep going, don't rush too much, because you can easily become overwhelmed by enemy fire power. Pace yourself and eventually you'll corner him. You'll be ordered to restrain him (however to no avail), make your way towards Imran Zakhaev, the screen will fade and voila.
